In 1960, a suspect in a Finnish triple homicide arrived at a Helsinki hospital the morning after the killings with clothing that attending physicians described as bloodstained. His fingernails were caked with dark material. He was incoherent and aggressive. ABO blood typing — a forensic procedure available since 1901 and routine in clinical and criminal laboratories worldwide by 1960 — could have determined within hours whether the stains were human blood and, if so, which blood type. The clothing was never tested. The suspect was released and never charged. He died decades later, confessing on his deathbed to a different unsolved killing. Construct the most plausible institutional explanation for why a hospital and police force in a developed Scandinavian nation in 1960 would fail to test bloodstained clothing on a man presenting symptoms consistent with involvement in a violent crime committed the previous night, fourteen miles away.
